i might have jumped into this late, but ive been away. a shorter rod is not needed but i reccomend it. being somewhat new to flyfishing, fishing brushy streams can be tedious with a long rod. i recommend a 7ft rod. cabelas has some combo rods that are around that price range. as far as breaking it....they have a 25 year warrenty.
i do highly recommend polorized sunglasses,but be careful. i wouldnt buy ones that are mirrored on the outside. we spend so much time wearing drab clothes do u want bright colors all around your eyes? now with that said, you also might not need them for some streams. brookie streams are often clear and in heavy shade. the amount of sun that gets through the dense woods can be minimal, meaning less glare. also brookies often hide in rocks,undercuts and any form of cover on the streambed and u might not see them anyways. but they do hang around the ends of pools and that is were these sunglasses come in handy. also when the sun does get through the trees you dont want your "mirrored" glasses casting a light beam at the fishes eyes!
but get polorized glasses. and go cheap....mine are a 5 dollar pair.
camo is not needed but i also recommend it. you can wear dark green,light green and brown clothes. i do wear camo sometimes....but it is not needed. if you already have some camo clothes, use them. if not you dont need to buy it.
i have seen no significant differnce in fish reaction to fly line. but get good line! dont go cheap here.
most important thing as stated before is stealth. approaching small stream trout is 90 percent of the game. good luck!
p.s. almost forgot. picking spots can be the best way to fish a small stream. in the summer larger brookies can hold in the largest holes. but dont be fooled!it is best to fish a whole stream the first few outings. find where the fish are then pick your spots. trout will move around also. by picking spots off of the bat, you may be missing out on some of the best fish and fishing in a watershed. we dont know why fish will sit where they do.....it may be under ground springs, extra food supply, or better habitat....only they know why they do what they do. we just catch them! :-D
